On the topic of stripper clips....

[MissingSomething]

I got this with some US - RA 40 .30-06 British contract dummy rounds....

The clip looks like a standard US .30 M1 5 round clip with the side tabs to keep the ammo in place.

Anyone recognize the symbol/manufacturer? Looks like a backward C with a T inside.

Have a look at this thread on the IAA forum, it's still an unknown makers symbol
